Locus of evaluation

Effort Task difficulty Additional research led to the hypothesis that typical expectancy shifts were displayed more often by those who attributed their outcomes to ability, whereas those who displayed atypical expectancy were more likely to attribute their outcomes to chance. This was interpreted that people could be divided into those who attribute to ability an internal cause versus those who attribute to luck an external cause. Bernard Weiner argued that rather than ability-versus-luck, locus may relate to whether attributions are made to stable or unstable causes.

Since at least as early as2 alpha loci have been known to exist in some humans Brimhall et al. The alpha locus is apparently double in Chinese Kan,whereas in American blacks, chromosomes with single or double alpha loci are about equally frequent Huisman, Rucknagel and Dublin estimated that a chromosome with a single alpha locus has a frequency of about 0.

They suggested that the former persons have 2 alpha hemoglobin loci and the latter persons 1 such locus. From studies of hemoglobin G PhiladelphiaBaine et al. In Melanesians, Eng et al. Michelson and Orkin stated that the genes encoding the alpha-like chains of human hemoglobin form a cluster on the short arm of chromosome 16 that spans approximately 30 kb.

What is Locus of Control?

Notably, this function is unique to hemoglobin alpha and is abrogated by its genetic depletion. The authors suggested that this model may be relevant to heme-containing globins in a broad range of NOS-containing somatic cells.

One, termed leftward, shows a deletion of 4. It is prevalent in most tropical and subtropical populations that have been studied, including African and American blacks, Mediterraneans, Southeast Asians, and some Pacific Island populations.

In contrast, the 4. The leftward one was found only in Asian cases until the report of a case in East Sicily Troungos et al. El-Hazmi found several persons with the leftward deletion alpha-thalassemia in Saudi Arabia, including homozygotes and heterozygotes. Remarkably, in north coastal Papua New Guinea, the 4.Deisseroth et al.

() combined the methods of somatic cell hybridization and DNA-cDNA hybridization to establish assignment of the alpha-globin locus to chromosome This represents an extension of the cell hybridization method permitting mapping of genes that are not functional in the cultured.
